W. Va. Code § 30-29-6
Certification of each West Virginia law-enforcement officer shall be reviewed annually following the first certification and until such time as the officer may achieve exempt rank. Certification may be revoked, suspended or not renewed if any law-enforcement officer fails to attend annually an in-service approved law-enforcement training program, or if a law-enforcement officer achieving exempt rank fails to attend biennially an approved in-service supervisory level training program. When a law-enforcement officer is a member of the United States Air Force, Army, Coast Guard, Marines or Navy, or a member of the national guard or reserve military forces of any such armed forces, and has been called to active duty, resulting in separation from a law-enforcement agency for more than twelve months but less than twenty-four months, he or she shall attend and complete the mandated in-service training for the period and rank and qualify with his or her firearm within ninety days from his or her reappointment as a law-enforcement officer by a law-enforcement agency.
